在美国内不拉斯加洲,在80英里的州际公路中有7.3英里的一段直线公路是用将废旧轮胎碎片渗入普通沥青中铺设而成的,看看那平整的路面我们就知道这项实验是成功的。时间和气候将决定这项试验计划是否能够满足建造更长使用寿命的快速公路的需要。实验用了将近47000片碎橡胶片。结 In the United States, no one in Las Americas, a section of the 7.3-mile stretch of the 80-mile interstital is paved with regular tire fragments of scrap tires. Look at the level of the road and we know that The experiment is successful. Time and climate will determine whether this pilot scheme will meet the need for a freeway for longer life.
